What you'll learn

The most powerful tool in a developer's toolbelt is an accurate mental model. Understanding React's internal architecture helps you write performant applications and debug complex issues with confidence. In this course, React's Internal Architecture, you'll learn to understand how React works under the hood to make better architectural decisions and optimize your applications. First, you'll explore React's fiber architecture and how the reconciliation algorithm efficiently updates the DOM. Next, you'll discover how React's event system works and triggers state updates that lead to re-rendering cycles. Then, you'll see how state and hooks are managed inside React. Finally, you’ll learn how useEffect works under-the-hood. When you're finished with this course, you'll have the skills and knowledge of React's internal architecture needed to build more performant React applications and debug issues with greater clarity and confidence.
